Abstract

A micro electromechanical ink jet printing system that has a cartridge having a body that defines a core, and a die that contains one or more nozzles. There is a treatment composition contained within the cartridge core. The system further includes a CPU that is programmable and can control the application of the treatment composition from within the cartridge core, through the one or more nozzles to human skin. Typically, the treatment composition will contain a skin treatment ingredient selected from the group consisting of particles, vitamins, yeast and yeast extracts, skin care actives, dyes, colorants and mixtures thereof. There may optionally be provided a bladder or foam block disposed within the cartridge core for suspending and regulating the flow of the treatment composition. The systems of this invention may include an applicator having an applicator head having one or more applicator nozzles which may be in a array. The applicator has a sensor that takes an image of at least 10 μm2 of skin, the CPU analyzes the image to calculate one or more localized L values of individual pixels or group of pixels of the skin. Then the CPU compares the local L value to a predetermined…
